Description
(1) technical field
What the present invention relates to is a kind of smooth tweezer, particularly a kind of light tweezer based on the toroidal cores capillary fiber.The present invention also relates to a kind of preparation method of smooth tweezer.
(2) background technology
The light tweezer is meant the instrument that fine particle was captured and handled to the gradient force that utilizes light intensity distributions and light scattering power.Since Askin[A.Ashkin in 1986, J.M.Dziedzic, J.E.Bjorkholm, and S.Chu, Observation of a single-beam gradient force optical trap for dielectric particles, Opt.Lett.11,288-290,1986] single beam laser is introduced high-NA objective and formed the three-dimensional optical potential well, after having realized three dimensions control to particle, optical tweezer technology develops by leaps and bounds becomes important investigative technique means, and has promoted the fast development of some crossing domains.For example: fine particle catch and the fields such as assembling of carrying, skin ox level force measurement, micromechanics and micro element are widely used.At life science, optical tweezer technology is contactless with it, the intrinsic propesties of lossless detection has shown its impayable advantage especially, has brought into play enormous function for the manipulation that promotes development of life science and little life entity.The particle size that the light tweezer is captured can be rigid particles from several nanometers to tens micron, also can be soft material grains; Can be abiotic particle, also can be active somatic cell or virus.
Tradition light tweezer normally makes up based on optical microscope system, and it focuses on laser beam by microcobjective, utilizes near the gradient field of force of focusing center to form ligh trap, and fine particle is caught and handled.Tradition optical tweezer technology maturation, but its complex structure and shortage are flexible, bulky, cost an arm and a leg, and ligh trap mobile system complexity, operative skill requires high.For this reason, optical waveguide optical tweezer technology scheme has been proposed, realize [Lu Si, Yang Changxi, the Zhou Zhaoying of catching of fine particle by means of a plurality of waveguide channels on same block of material matrix, optical waveguide optical spanner system, Chinese invention patent, publication number CN1740831A], to have a volume bigger in view of this optical waveguide optical tweezer end, the big deficiency of preparation difficulty, people have further developed optical fiber optical tweezers technology [A.Constable, J.Kim, J.Mervis, F.Zarinetchi, and M.Prentiss, Demonstration of a fiber-opticallight-force trap, Opt.Lett.18,1867-1869,1993; Zhihai Liu, Chengkai Guo, JunYang, and Libo Yuan, Tapered fiber optical tweezers for microscopic particletrapping:fabrication and application, Optics Express, 14 (25), 12510-12516,2006].Optical fiber optical tweezers is simple in structure, can make the miniature probe form, and ligh trap and manipulation thereof separate with optical microscope system, so the ligh trap manoeuvrable, and degree of freedom in system is big.There is the comparatively advanced optical fiber optical tweezers technology of several technology in the existing technology formerly, as: the end surface grinding of two single-mode fibers is become cone, at hemisphere face of the most advanced and sophisticated formation of cone, make outgoing beam have the weak focusing characteristic, become certain optical axis included angle to place these two optical fiber, the ligh trap that the overlapping light field forms can be realized capture particles and suspension [E.R.Lyons and G.J.Sonek, Confinement and bistability in a tapered hemispherically lensed optical fiber trap, Appl.Phys.Lett.66,1584-1586,1995]; Publication number is the patent of invention of CN 1963583A becomes to have parabolic microstructure with an end melting and pulling of one section optical fiber an optical fiber pin.With laser coupled in the other end of optical fiber, the light field that converges that laser forms at optical fiber pin front end after the outgoing of optical fiber pin less than 1 micron waist spot diameter, can form stable three-dimensional light potential well, thereby realize single fiber optical tweezers [Liu Zhihai, the garden vertical wave, Yang Jun, the melting and pulling of parabolic microstructure single fiber optical tweezers is made method, Chinese patent, publication number CN 1963583A]; The Chinese invention patent of publication number CN101118300 has provided a kind of small core diameter ultra-high numerical aperture cone optical fiber optical tweezers and preparation method thereof.It adopts small core diameter ultra-high numerical aperture optical fiber to process, and its optical fiber end is ground into cone shape.Disperse light field and can form bigger light field gradient force potential well owing to what the large-numerical aperture of this fiber optic tip formed, thereby can overcome the deadweight of particle, realize single fiber three-dimensionally capturing [garden vertical wave, Yang Jun to fine particle, Liu Zhihai, the ultra-high numerical aperture cone optical fiber optical tweezers technology].For the further attitude to the fine particle of being caught is controlled, publication number is to have provided a kind of twin-core fiber light tweezer [garden vertical wave again in the Chinese invention patent file of CN101149449; Liu Zhihai; Yang Jun is used for twin-core single fiber optical tweezers of capturing minute particle and preparation method thereof].
Although the above-mentioned technology formerly that constitutes the light tweezer by optical fiber has certain advantage, but still comes with some shortcomings.For example, for the particle of catching, deposit nowhere.For quantity bigger a plurality of particle carryings and assembling task, it handles with efficiency of assembling low.
(3) summary of the invention
The object of the present invention is to provide a kind of particle that not only can catch, but also can deposit particle, be more suitable in the capillary pipe optical fibre light forceps of the bigger a plurality of particles carryings of quantity performed with the assembling task.The present invention also aims to provide a kind of method for making of capillary pipe optical fibre light forceps.
The object of the present invention is achieved like this:
